North Korea doesn’t need nuclear weapons to protect themselves. China has their back. American leadership would not attack North Korea if they didn’t have nukes. China has made it clear they will not allow it. China and America are economically co-dependent at this point, and will be for a long time. And why would America attack North Korea except for fearing nukes? Iraq, Libya, Syria, these countries were part of a long term plan to take away their oil and or alliance with Iran. North Korea is not the same. A big fear is that North Korea is going to sell nuclear weapons. That is the main reason that has the aristocrazies in a tizzy. North Korea doesn’t need nuclear weapons to protect themselves, yes they may not be crazy, but they are poor, and hate America. That means while they may not be crazy enough to try to start something with America, even though they certainly act crazy by inviting more harm to themselves then need be, they may be crazy angry enough to sell nukes to the highest bidder.
